About the Loan Comparison Calculator

Loan Comparison Calculator puts two loan offers next to each other. For Loan A and Loan B, enter the amount, annual interest rate, term in months or years, and any upfront (origination) and monthly fees. Each loan uses the standard monthly amortisation formula, and the tool shows the estimated monthly payment, total interest, upfront and recurring fees, total cost, total paid and an estimated effective cost that includes the fees.

A neutral summary states the differences — for example whether Loan A’s total estimated cost is higher or lower than Loan B’s under the entered assumptions — without ranking either offer. Monthly schedules for both loans can be viewed and downloaded as CSV. The effective cost is an estimate, not a legal APR disclosure; lenders’ APR calculations, compounding, prepayment rules, insurance, taxes, penalties, variable rates and eligibility can all differ, so check each lender’s official documents.

How to use

  1. Enter Loan A’s amount, rate, term and any fees.
  2. Enter the same details for Loan B.
  3. Choose a currency symbol.
  4. Press Compare to see both loans side by side.
  5. Review the difference summary and schedules, then copy or download.

Frequently asked questions

How is the monthly payment calculated?

With the standard amortisation formula P × i ÷ (1 − (1 + i)^−n), where i is the annual rate ÷ 12 and n the number of months. At 0% interest the payment is the amount divided by the number of months.

How are fees included?

Upfront fees are treated as paid at the start and added to the total cost. Monthly fees are added to every payment. Neither changes the interest calculation.

What is the estimated effective cost?

It is the yearly rate at which the amount you actually receive (the loan amount minus the upfront fee) equals all your payments and monthly fees. It helps show the effect of fees but is an estimate, not a legal APR disclosure.

Does the tool tell me which loan to choose?

No. It only shows the figures and neutral differences under the values you entered. Other factors — flexibility, prepayment rules, insurance, variable rates and eligibility — are not included.

Can I compare loans with different amounts or terms?

Yes. The summary points out when the amounts or terms differ, because total paid is then not a like-for-like comparison.

What are the limits?

Loan amounts above zero up to 1 trillion, rates from 0% to 50%, terms of 1 to 600 whole months (50 years), and upfront fees below the loan amount.

Does the currency selector convert amounts?

No. It only changes the symbol shown (₹, $, €, £ or none). No exchange rate is used and the calculation is identical whichever symbol you pick.

Is anything I enter stored or sent anywhere?

No. Calculations run in your browser on your device. Amounts, rates, results and tables are not uploaded and are not saved in browser storage. Reset clears them from the page.
